Pets are cute! But very helpless, especially so during times of emergency. So what happens when they're stuck in a fire and suffering from smoke inhalation and, well, need oxygen? Fire trucks in Denver are starting to get pet-specific oxygen masks to pump that good stuff into them.

These masks aren't new, veterinarians have been using them for years to apply anestesia, but it's pretty cool that fire trucks have started to adopt them since masks designed for humans aren't as effective when used with dogs. They like to breathe just as much as we do, after all. The pet oxygen masks sets were donated by Invisible Fence and come in three different sizes. Over the years, Invisible Fence has donated 10,000 masks and saved over a 100 dogs lives with these masks. [AP YouTube]
